How to put java files in *.jar

I have 5 *.java files in 1 directory. I want to put those 5 classes in a *.jar file without using some special tool. How is the best way to do that.
It is something with the command prompt?
All help welcome.

What is a 'special' tool?
If you want to write your own jar app then feel free. You should probably need to do some research on zip files.
If not then I suggest you use "jar" which will put anything into a jar file that you want.

Hi
Just for completeness, what version of VB.NET are you using?
Here is a complete project to copy all the files with the added "ABL," at the start of each line. You need to start a new Project with a BLANK default Form1, and replace all of Form1 code with the code below. When you run this project, you
need to use the 2 buttons to set up the ORIGINAL file folder and a folder to place the copies. You need to check if the file EXTENSION is correct (I assumed txt), and check the text to add to each line is correct. Once all is set up you should have a
big red button to start the operation.
NOTE: it is important that you try this out on a copy of some of the files to verify accuracy BEFORE trying on original files. Make sure you have a good back up of the original files before doing anything else.

Its urgent how to use calss file of jar located in lib folder

how to use calss file of jar located in lib folder.
i want to use RowSetDynaClass class which is in beanutil jar file which is in my lib folder .if i use that class in my jsp following error is coming.
Class RowSetDynaClass not found.
RowSetDynaClass resultSet = new RowSetDynaClass(rs, false);
how to access class in jar file.
please help

You have to either refer to the class in its fully quallified name, or import it into the JSP:
<%
some.full.packagename.RowSetDynaClass resultSet = new some.full.packagename.RowSetDynaClass(rs,false);
...-or-
<%@ page import="some.full.packagename.RowSetDynaClass" %>
<%
RowSetDynaClass resultSet = new RowSetDynaClass(rs, false);
...As long as the class has public visibility and you have re-started the server/servlet context since you added the JAR.

How to search .java files by Search tool in NWDS or any other tool?

Hi All,
I can easily search .JSP files by NWDS's Search tool, but I have a hard time to search Java files by this tool. Can anyone guide me how to search Java files which contain a specified string by using Search tool in NWDS? or any other tool?
Thanls. Jin

Hi Jin,
You can search Custom Java files with NWDS Search tool for specified string. But not standard Java files.
Suppose you have extend z_userR3 base on UserR3 and contains string some help then you can click on search in NWDS
Then click on File it will open Search box with 4 tag
1. File Search
2. Help Search
3. Java Search
4. Plug-in Search
Click on File Search tab and provide the text in Containing text input box and give java file name with wild characters like *.java
Select Workspace under Scope and hit search button. It will search string in your custom Java file. This method will not search string in Standard Java classes of SAP.
If you want to search in standard SAP java classes then you should know about what you are searching i.e. whether it is field, Method, Package, Constructor and Type select proper radio button under Search For box then tryo to select proper radio button under Limit To if you want to search everywhere then select All Occurrences. You should select Workspace under Scope.
Suppose nothing comes after selected Type then go for other option one by one Method, Field etc...
Expert people will give you more information.
I hope this will help you.
Regards.

How to put picture files and other things on my BB 8703e

Hello! I know I got a bit of a throwback bb, but I am using it until I can upgrade to a new phone on sprint.
So, I am barely learning about this bb, so any help or cool uploads and apps I need to add... Please let me know.
Now I got this app, that will supposedly let me play music files. However, i cannot seem to figure out how to put any files on here when I connect my bb to my computer. When I initially connect the usb it will be like BB connection detected, but it doesn't show a folder or anything...
Where should i be looking....
What should I do?

With the 8707, I believe you will need to visit a website and download the image from there, or from an email you send with the image attached.
Music or ringtones will need to come from visiting a site with music or ringtones, from the BlackBerry browser.

How to run .java file in windows ?

after those, you must complie your .java file to .class file, then you can excute it by java, for example " java helloworld"

How to put native methods in jar file

Hi.I have an executable jar file(test.jar) that makes use of other jar files and native methods. For example, test.jar uses Jnpout32.dll. . test.jar , the other jar files and the native methods are all in the same directory. When I created test.jar I wrote a manifest file which specifies the class path of the other jar files and the native methods as follows and provided it as an option in the jar cfmev command.
Class Path: jdbc.jar Jnpout32reg.dll //content of manifest.txt file that I provided to the jar command
//carriage return I then run the command java -jar test.jar to run the file.
All I am seeing is the following error message
Exception in thread "AWT EventQueue-o
"Java.lang.NoClassDefFoundError.
gnu/io/SerialPortEventListner"
{code}
Any ideas? thanks in advance!

You seem to be confusing Java's classpath with your os's path. The classpath only applies to Java classes. See if this discussion helps:

How to compile java files in a bunch of drectories?

I have a bunch of java files in a bunch of different directories. How can I compile them all at once? Please note I also do not know how to get javac to work outside the java directory.

Is it necessary to put .java file in 'bin' folder

when ever i am creating a .java file i have to put that in bin folder then only javac compiling the file.
otherwise its not compiling the file.
how can i compile my java file by putting in any folder of mine?
even if i am creating any folder inside the bin folder then also its not compiling my .java file.

when ever i am creating a .java file i have to put
that in bin folder then only javac compiling the
file.That's a huge mistake. You should never do that.
otherwise its not compiling the file.
how can i compile my java file by putting in any
folder of mine?Add the Java /bin directory to your PATH so the operating system can find the javac.exe and java.exe apps.
even if i am creating any folder inside the bin
folder then also its not compiling my .java file.Then you've got a bigger problem. You must have compiler errors that you need to read and fix in your source code.

There is a common approach to this problem which is a dependency repository. Various build tools address the dependency resolution problem. Most common are maven and greadle. Place your Jar file on a location you can reach from your various developement environments (eg. a share on a server in your network) Then configure your build tool to know about your repository.
A better solution that a naked net share is a nexus server, which will not only hanlde dependencies you namually placed on your share but also dependencies available on public repositories.
In your project you simply declare the (direct) dependencies of the Code you're writing. For maven you need an aditional file in your project: the pom.xml. maven (or greadle) will handle all the transient dependencies for you (as long as the pom.xml of the dependency also declares its own dependencies and those other dependencies are reachable for maven too).

How to pack image files in jar and reference them

How to compile java file in Tomcat ?

Hi all,
I have a java file named Ch1Servlet.java under project1/src directory
there is classes directory project1/classes and web.xml under src directory
project1/src directory.
Now to compile i have to give %javac -classpath /your path/tomcat/common/lib/servlet-api.jar -d classes src/Ch1Servlet.java
What is this your path ? Tomcat 5.0 is installed in C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib with servlet-api.jar
Please help me out.
Best Regards
Taton
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class Ch1Servlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
PrintWriter out = response.getWriter();
java.util.Date today = new java.util.Date();
out.println("<html>"+"<body>"+"<h1 align = center>HF\'s Chapter 1 Servlet</h1>"+"<br>"+today+"</body>"+"</html>");
}

understand 1 thing..ur tomcat is not a compiler as u
think..its a poor web server only..
Its not mandatory that u need to put the source files
in tomcat folder.u can put ur java files where ever u
want..put servlet.jar in ur classpath.
then start compiling ur java files..once u are done
with compiling copy the class files alone to ur
web-inf classes folder.
thats it!!!

How to launch java files on Mac OS

Hey! I got a question: how to wrap a java file into Mac OS executable file? Analog for Windows is exe4j . It creates a jre in a exe file , so a person dont need to install runtime env. So any way to do like that? I need to launch program on Mac OS without terminal & installed jre. Just double-click on icon. Thanx for response.

won't work. The question is how to execute a Java source file as a Mac executable.I don't think that's what the OP wants. To quote him:
I need to launch program on Mac OS without terminal & installed jre. Just double-click on icon.Sounds exactly as if he'd like to have an executable jar file. And since Mac OS X comes with a JRE preinstalled, there is no more magic necessary to make it easily usable.
